One of the challenges of traveling to a city you don't know, is getting around - depending on the city, the bus or the metro may be the best option. But when you're on a metro it can sometimes be hard to figure out where to get off the train. In London where you speak the language it's not too hard. If you travel to Paris things get a little more complicated since there is a language barrier. A city where they use a different alphabet makes it much harder.
Here is my tip - take a picture of the name of the metro stop. When all else fails you can refer to the picture on your digital camera, and this works anywhere, not just in a city with a different alphabet. If you're drunk in Berlin and can't remember the name of your stop you can refer to your picture, and if you're really drunk you can get a local to help you with your picture.
